No-scale and scale-separated flux vacua from IIA on G2 orientifolds
Fotis Farakos, George Tringas, Thomas Van Riet
We discuss flux compactifications of IIA string theory on G2 holonomy spaces with O2/O6-planes to three dimensions and find two classes of solutions: 1) No-scale Minkowski vacua fr…
Three-forms and Fayet-Iliopoulos terms in Supergravity: Scanning Planck mass and BPS domain walls
Niccolò Cribiori, Fotis Farakos, George Tringas
We embed a new three-form vector multiplet in supergravity and we show that it can be used to generate dynamically the Hilbert--Einstein term. We then recast the theor…
PBH remnants as dark matter produced in thermal, matter and runaway-quintessence post-inflationary scenarios
Ioannis Dalianis, George Tringas
We investigate the cosmology of mini Primordial Black Holes (PBHs) produced by large density perturbations. The mini PBHs evaporate promptly in the early universe and we assume tha…
Electromagnetic probes of primordial black holes as dark matter
Y. Ali-Haimoud, S. Clesse, J. Garcia-Bellido +91
The LIGO discoveries have rekindled suggestions that primordial black holes (BHs) may constitute part to all of the dark matter (DM) in the Universe. Such suggestions came from 1)…
